: Created by Shuusuke Shunjou , the manga was serialized and later collected into a single volume featuring four chapters, published between 2019 and 2020.

The plot of Ano Ko no Kawari ni Suki na Dake centers around a complex, forbidden domestic relationship. The story begins with a mother whose daughter has married an seemingly ideal man: he is tall, muscular, polite, and possesses a highly promising career. However, domestic tension arises when the mother stumbles upon revealing clothing left behind by her daughter.

The catalyst for the entire series occurs when Minako is left alone in her daughter's home. While looking through some old clothes that Reina had left behind, she stumbles upon something rather... revealing . Among the clothes is a set of extremely skimpy lingerie and a cheerleader's uniform. On a whim, perhaps out of curiosity or a desire to recapture her youth, Minako decides to try them on. It is at that exact moment that Akio returns home and, not seeing his wife, mistakes Minako from behind for Reina. He approaches her from behind, overcome with desire, and begins to initiate an intimate encounter, unaware that it is his mother-in-law.

: The title highlights the concept of replacement. The protagonist channels his desires toward a substitute, creating a dual layer of guilt and intense emotional dependency.
